Even this challenging situation would ease
In TV shows you will have some audience who will be observing you and with that, they may get some stage fear and hence they may not be able to act well. In Live shows, there are no chances for editing and retakes. They require a lot of skill.
Coming to the subject of general knowledge, the level of understanding will vary from person to person and we can't expect the same performance from all the actors. Some may have a good understanding of the subject and some may not have. We can't generalise the issue and make a common statement.
Is GK an essential requirement for an actor? No. An actor is expected to deliver the written dialogue with body and facial movement and expression. They should listen to their directors and satisfy him. That's all. They need not have any IQ and GK. If they have it, we would appreciate them. Many actors may not be knowing who is the President and Prime Minister of India.
